First, the source code compilation

1. Source code Download

2, I Linux version Ubuntu 14.04 (gun/linux 3.13.0-0-32-generic x86_64)

3. Prerequisite Preparation

$sudo apt-get Install GCC

$sudo Apt-get Install Libbsd-dev

$CD apue.3e

Make

.. Wait for compilation to complete

Ii. Examples of essays

1, author makefile

Example of the first LS in Chapter one (APUE.3E/INTRO/LS1.C)

First Makefile (Apue.3e/makefile)

A second Makefile (Apue.3e/intro/makefile)

Tempfiles=core core.* *.o temp.* *.out

2. Complete the code in the self-built working directory

Copy the codebase to your own directory (MYAPUE)

Building the first chapter code catalog

$mkdir CH1

$CD CH1

Then copy the apue.3e makefile to CH1, remove the values that need to be traversed in the progs to add your own new file

First example: Vim MYLS.C

/ * CommentEssays*///DIR:struct__dirstream {void*__fd; Char*__data; int__entry_data; Char*__ptr; int__entry_ptr;        size_t __allocation;        size_t __size; __libc_lock_define (, __lock)};typedefstruct__dirstream DIR;//dirent <dirent.h>structdirent{LongD_ino;/*inode Number*/off_t D_off; /*offset to this dirent*/unsigned ShortD_reclen;/*length of this d_name*/    CharD_name [name_max+1];/*file name (null-terminated)*/}

After saving exits, add myls (progs = Myls) in the progs of makefile

$make

./myls/home can list files in the/home directory
